The effects of temperature on the percentages of
PDIV and DM of HWEM when the processing time
was fixed at 4 h are shown in Figure 1a. Although a
significant increase occurred in percentage of DM at
each increased temperature level, 75°C was chosen for
further processing because the percentage of PDIV derived
at 90°C was significantly lower than that derived
at 75°C. The influences of processing time on the percentages
of PDIV and DM of HWEM produced at the
fixed temperature of 75°C are presented in Figure 1b. A
significant increase in percentage of DM with increased processing time was observed
